Description

Technical Field

[0001] This invention relates to the field of deep-sea cage technology, and in particular to a lifting deep-sea cage structure. Background Technology

[0002] Cage aquaculture is an important model of modern aquaculture. As the core component of the cage, the netting is constantly immersed in seawater, making it highly susceptible to the adhesion of algae, shellfish, and other marine organisms. This hinders water exchange between the inside and outside of the cage, leading to water quality deterioration and negatively impacting the health and growth of farmed fish. Therefore, regularly replacing and cleaning the netting is an essential maintenance procedure in cage aquaculture.

[0003] Currently, the traditional method of changing fish nets mainly relies on divers diving underwater. This method has many drawbacks: First, diving operations pose high safety risks and require highly skilled divers, resulting in huge labor costs; second, the entire replacement process is time-consuming and inefficient, seriously affecting the normal operation of aquaculture production; third, during the replacement process, the new net needs to be placed over the old net before the old net is brought to the surface, which greatly frightens the fish, causing them to violently collide in the confined space, easily leading to damage to their body surface, loss of scales, and even infection and death, causing direct economic losses to fish farmers. Summary of the Invention

[0004] In view of the above-mentioned prior art, the present invention provides a lifting deep-sea cage structure that enables operation on water, is highly efficient and convenient, and can minimize stress and damage to fish.

[0005] To achieve the above objectives, the technical solution of this invention is implemented as follows: A lifting deep-sea cage structure includes a float, an inner support frame, an outer support frame, a net, a track, and anchor piles. The float is connected to the anchor piles by a fixing rope. The float is fixedly connected to the outer support frame. The inner support frame is detachably connected to the outer support frame. The track is provided on the outer support frame. The track is provided with a slider. The inner support frame is slidably connected to the track. The net is provided on the inner support frame.

[0006] Furthermore, the track includes a left track and a right track, and the slider is provided on both the left track and the right track. The two sliders are connected by a fixed shaft. The inner support frame is rotatably connected to the fixed shaft. The inner support frame is provided with an upper lever and a lower lever on both sides. Both the upper lever and the lower lever are provided with hooks.

[0007] Furthermore, the inner support frame includes a connecting frame, a snap-fit ​​frame, and pins. The connecting frame is used to connect the mesh, the snap-fit ​​frame is snapped into the outer support frame by a snap-fit ​​mechanism, and the connecting frame is connected to the snap-fit ​​frame by a plurality of pins.

[0008] Furthermore, the connecting frame is provided with several rope holes.

[0009] Furthermore, a U-shaped rod is rotatably connected inside the connecting frame. The rotation center of the U-shaped rod is parallel to the fixed axis. The connecting frame is provided with a first limiting stop. The U-shaped rod can rotate from a vertical position to a vertically upward position after passing near the fixed axis. When the U-shaped rod rotates and abuts against the first limiting stop, the U-shaped rod is perpendicular to the connecting frame.

[0010] Furthermore, the clamping mechanism includes an upper rotating column, a lower rotating column, and a connecting rod. The upper rotating column is rotatably connected to the outer support frame, and the lower rotating column is rotatably connected to the clamping frame. The outer support frame has an upper cylindrical groove, in which the upper rotating column is rotatably connected. The upper rotating column is connected to an upper operating rod, which is connected to an upper spring plate. The outer support frame has a connecting groove communicating with the upper cylindrical groove. The upper rotating column has a first clearance groove extending from the side to the axis, which is inclined downwards in its natural state. The clamping frame is rotatably connected to the connecting rod, which has a lower cylindrical groove. The lower rotating column is rotatably connected within the lower cylindrical groove. The lower rotating column is semi-cylindrical, connected to a lower operating rod, which is connected to a lower spring plate. In its natural state, the plane of the lower rotating column is inclined upwards.

[0011] Furthermore, the snap-fit ​​frame is provided with a second limiting stop bar, which is located on both sides of the plug-in rod, and the plug-in rod can rotate within a range of 5 to 15 degrees.

[0012] Furthermore, the length of the first clearance groove is greater than the length of the lower rotating column.

[0013] Furthermore, the inner support frame is a rectangular frame, and the width of the rectangular frame is less than 0.5 times the depth of the left and right tracks.

[0014] The advantages of this invention are as follows: When replacing the old netting, workers do not need to dive underwater; when installing the new netting, the operation can be carried out directly on the floating platform, making installation more convenient and efficient. After the new netting is installed, the new netting, old netting, and inner support frame are submerged together in the water. A floating crane is used to flip them over, pulling the old netting to the surface while the fish swim into the new netting. Workers then remove the old netting from the floating platform. The entire operation takes place above the water surface, making removal more convenient and efficient. During the flipping process, the fish remain underwater, and the large underwater space reduces stress and surface damage to the fish during net replacement. Attached Figure Description

[0018] Please refer to the attached document. Figures 1-6This application provides a lifting deep-sea cage structure, including a float 1, an inner support frame 2, an outer support frame 3, a net 4, a track 5, and anchor piles 6. The float 1 is connected to the anchor piles 6 via a fixing rope 7. The float 1 is fixedly connected to the outer support frame 3. The outer support frame 3 is detachably connected to the inner support frame 2. The outer support frame 3 is equipped with the track 5, and the track 5 is equipped with a slider 8. The inner support frame 2 is slidably connected to the track 5 and is equipped with the net 4. The float 1 floats on the water surface and is connected to the anchor piles 6 via the fixing rope 7. The anchor piles 6 are firmly anchored to the bottom of the water, serving to fix and position the cage. The outer support frame 3 is fixed to the inside of the float 1, and the inner support frame 2 is detachably connected to the inside of the outer support frame 3. The inner support frame 2 is rotatably connected to the slider 8, and the slider 8 is slidably connected to the track 5, allowing the inner support frame 2 to move up and down and also to rotate. In daily aquaculture, the net 4 is fixedly connected to the inner support frame 2, and the inner support frame 2 is connected to the outer support frame 3. The net 4 forms a net that surrounds the fish. After prolonged use, other marine organisms will attach to the net 4, affecting its permeability and causing the water quality inside the net 4 to fail to meet requirements. At this time, a new net 4 is connected to the inner support frame 2, and then the hook of the floating crane is connected to the inner support frame 2. The inner support frame 2 is then separated from the outer support frame 3, and the inner support frame 2 slides down along the track 5 into the water. The floating crane is used to pull one side of the inner support frame 2 upward, causing the inner support frame 2 to flip over. The new net 4 rotates to the bottom, and the positions of the upper and lower nets 4 are swapped. After the old net 4 is pulled up, the fish pass through the inner support frame 2 into the new net 4. Finally, the inner support frame 2 is reconnected to the outer support frame 3, and the old net 4 is removed, completing the replacement of the net 4. This invention eliminates the need for workers to dive underwater when replacing the old netting 4, and allows for direct installation of the new netting 4 from the float 1, making installation more convenient and efficient. After installation, the new netting 4, the old netting 4, and the inner support frame 2 are submerged together. A floating crane is used to flip them over, pulling the old netting 4 to the surface while fish swim into the new netting 4. Workers then remove the old netting 4 from the float 1. The entire process takes place above the water surface, making removal more convenient and efficient. During the flipping process, the fish remain underwater, and the large underwater space reduces stress and surface damage to the fish during the net replacement process.

[0019] Specifically, the track 5 includes a left track 9 and a right track 10, each equipped with a slider 8. The two sliders 8 are connected by a fixed shaft 11. The inner support frame 2 is rotatably connected to the fixed shaft 11. The inner support frame 2 has an upper lever 12 and a lower lever 13 on both sides, each equipped with a hook 14. After the inner support frame 2 slides to the bottom, the left track 9 and right track 10 support the inner support frame 2 and the netting 4 from both sides, ensuring the balance of the net cage aquaculture system and preventing the float 1 from overturning after the inner support frame 2 slides to the bottom. The sliders 8 are connected by the fixed shaft 11, allowing the two sliders 8 to move up and down synchronously. The inner support frame 2 is rotatably connected to the fixed shaft 11. After the slider 8 slides to the bottom, the hook of the floating crane is connected to the hook ring 14 of the lower lever 13. After being lifted upward, the inner support frame 2 is rotated, and the positions of the new mesh 4 and the old mesh 4 are interchanged. The inner support frame 2 is then continuously pulled upward to lock the outer support frame 3 together. Finally, the worker removes the old mesh 4 and checks whether the connection between the inner support frame 2 and the outer support frame 3 is firm. Any parts that are not firmly connected are then connected and stabilized.

[0020] Specifically, the inner support frame 2 includes a connecting frame 15, a snap-fit ​​frame 16, and pins 17. The connecting frame 15 is used to connect the netting 4. The snap-fit ​​frame 16 is snapped into the outer support frame 3 through a clamping mechanism 18. The connecting frame 15 is connected to the snap-fit ​​frame 16 through several pins 17. When the floating crane pulls the lower lever 13 to flip the inner support frame 2 and lift it upward, the weight distribution on both sides of the inner support frame 2 is not completely uniform. The side with the old netting 4 is heavier, while the side with the new netting 4 is lighter, causing the inner support frame 2 to tilt slightly after being lifted. The snap-fit ​​frame 16 is located outside the connecting frame 15. After the inner support frame 2 is pulled upward, the upward-curving side of the snap-fit ​​frame 16 snaps into the outer support frame 3, while the downward-sinking side adjusts the old netting 4 and continues to pull upward, making the snap-fit ​​frame 16 of the inner support frame 2 firmly connected to the outer support frame 3. This invention automatically tilts the inner support frame 2 after it is pulled upwards. Under the action of gravity, the old netting 4 slides downwards, exposing the upward-curving snap-fit ​​frame 16. This prevents the snap-fit ​​frame 16 from trapping the old netting 4 when it engages with the outer support frame 3. After the snap-fit ​​frame 16 on the raised side engages with the outer support frame 3, the worker pulls the old netting 4 into the inner side of the inner support frame 2. This prevents the snap-fit ​​frame 16 on the lower side from trapping the old netting 4 when it engages with the outer support frame 3, and also drives any fish that have not yet entered the new netting 4 into the new netting 4.

[0021] Specifically, the connecting frame 15 is provided with several rope holes 19 to facilitate workers connecting the mesh 4 to the connecting frame 15.

[0022] Specifically, a U-shaped rod 20 is rotatably connected inside the connecting frame 15. The rotation center of the U-shaped rod 20 is parallel to the fixed shaft 11. The connecting frame 15 is provided with a first limiting stop 21. The U-shaped rod 20 can rotate from a vertical position, passing near the fixed shaft 11, to a vertically upward position. When the U-shaped rod 20 rotates and contacts the first limiting stop 21, the U-shaped rod 20 is perpendicular to the connecting frame 15. After the lower lever 13 is pulled upward, the connecting frame 15 tilts. At this time, the lower U-shaped rod 20 contacts the first limiting stop 21 and remains perpendicular to the connecting frame 15. The upper U-shaped rod 20 swings downward under the action of gravity, causing the upper old netting 4 to collapse downward, driving the fish towards the new netting 4. At the same time, the downward-swinging U-shaped rod 20 enters the new netting 4, pushing the new netting 4 open to facilitate the fish entering the new netting 4. The lever is pulled upwards until the top of the U-shaped rod 20 emerges from the water. The worker pushes the U-shaped rod 20 to flip it towards the fixed shaft 11. The old netting 4 collapses towards the connecting frame 15, and the net bag formed by the old netting 4 is basically collapsed, allowing the fish to enter the new netting 4. The U-shaped rod 20 can open the netting 4 during the aquaculture process, maintaining the aquaculture space inside the netting 4. During the replacement of the old and new netting 4, the U-shaped rod 20 also serves to open the new netting 4 and drive the fish into the new netting 4.

[0023] Specifically, the clamping mechanism 18 includes an upper rotating column 22, a lower rotating column 23, and a connecting rod 24. The upper rotating column 22 is rotatably connected to the outer support frame 3, and the lower rotating column 23 is rotatably connected to the clamping frame 16. The outer support frame 3 is provided with an upper cylindrical groove 25, in which the upper rotating column 22 is rotatably connected. The upper rotating column 22 is connected to an upper operating rod 32, which is connected to an upper spring plate 28. The outer support frame 3 is provided with a connecting groove 24 communicating with the upper cylindrical groove 25. 6. The upper rotating column 22 is provided with a first clearance groove 27 extending from the side to the axis. In its natural state, the first clearance groove 27 is inclined downward. The snap-fit ​​frame 16 is rotatably connected to a plug-in rod 24. The plug-in rod 24 is provided with a lower cylindrical groove 29. The lower rotating column 23 is rotatably connected in the lower cylindrical groove 29. The lower rotating column 23 is semi-cylindrical. The lower rotating column 23 is connected to the lower operating rod 33. The lower operating rod 33 is connected to the lower spring plate 30. In its natural state, the plane of the lower rotating column 23 is inclined upward. When the inner support frame 2 is lifted upward, the plug-in rod 24 pushes the lower rotating column 23 upward to insert it into the plug-in groove 26. Since the plane of the lower rotating column 23 is inclined upward in its natural state, and the first clearance groove 27 of the upper rotating column 22 is inclined downward, the intersection surface of the lower rotating column 23 and the upper rotating column 22 flips when they rotate under mutual pushing, so that the plug-in rod 24 can be smoothly inserted into the plug-in groove 26. After insertion, under the action of the upper spring plate 28 and the lower spring plate 30, the upper rotating column 22 and the lower rotating column 23 deflect, that is, a part of the upper rotating column 22 enters the lower cylindrical groove 29, and a part of the lower rotating column 23 enters the upper cylindrical groove 25, completing the locking. When it is necessary to release the locking relationship, the operator swings the upper lever 12 and the lower lever 13 to drive the upper rotating column 22 and the lower rotating column 23 to rotate, so that their meeting surface rotates to a vertical state. At this time, the upper rotating column 22 is located in the upper rotating groove, and the lower rotating column 23 is located in the lower rotating groove, and the insertion rod 24 can be disengaged from the insertion groove 26. The locking mechanism 18 of the present invention can lock after being connected, without the need for the inner support frame 2 to retract to lock the connection, and there is no need to lift the inner support frame 2 upward when releasing the locking. Preferably, the upper rotating column is in clearance fit with the upper cylindrical groove, and the lower rotating column is in clearance fit with the lower cylindrical groove. The clamping mechanism 18 is a non-rigid connection, allowing the inner and outer support frames to rotate relative to each other. This design makes it less susceptible to damage from wind and waves in the ocean. Under the influence of wind and waves, when the inner support frame 2 is pulled downwards, the bottom of the upper cylindrical groove 25 and the top of the lower cylindrical groove 29 experience force and friction; conversely, when the inner support frame 2 is pushed upwards, the top of the upper cylindrical groove 25 and the bottom of the lower cylindrical groove 29 experience force and friction. This design effectively restricts the vertical movement of the inner support frame 2. Furthermore, the relative movement and friction of the contact surfaces of the clamping mechanism 18 during wind and waves helps prevent corrosion and adhesion of the contact surfaces.

[0024] Specifically, the snap-fit ​​frame 16 is provided with a second limiting stop 31, which is located on both sides of the plug-in rod 24. The plug-in rod 24 can rotate within a range of 5 to 15 degrees. The plug-in rod 24 can rotate within a small range. When the inner support frame 2 is raised upward, one side of the inner support frame 2 tilts upward. After contacting the lower rotating column 23 with the upper rotating column 22, further lifting will push the plug-in rod 24 to rotate, aligning the lower rotating column 23 with the upper rotating column 22. It can automatically flip and align when the upper rotating column 22 and the lower rotating column 23 are tilted relative to each other, which facilitates connection.

[0025] Specifically, the length of the first clearance groove 27 is greater than the length of the lower rotating column 23. Even when the lower rotating column 23 is offset in the length direction after the inner support frame 2 is raised and tilted, it can still be stably inserted into the insertion groove 26.

[0026] Specifically, the inner support frame 2 is a rectangular frame, and the width of the rectangular frame is less than 0.5 times the depth of the left track 9 and the right track 10. The inner support frame 2, with its large length and small width, can remain underwater during the flipping process. The fish are always underwater during the flipping process, and the large underwater space reduces stress on the fish during the net changing process and reduces damage to the fish's body surface.

[0027] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. The scope of protection of the present invention should be determined by the scope of the claims.
